Steelers S Polamalu out vs. Chiefs (AP) (sports.yahoo.com)

Steelers safety Troy Polamalu did not practice all week because of a left knee injury and will not play Sunday in Kansas City. He may miss the Nov. 29 game at Baltimore as well. Polamalu sat out the Steelers' second through fifth games with a ligament tear, only to injure the same knee during an 18-12 loss to Cincinnati on Sunday.
